Enological eligibility of grape clones based on the simca method: The case of the sangiovese cultivar from tuscany

Sangiovese is the most widespread Italian red grape cultivar and it constitutes the basis of internationally known wines. It has a large diversity of clones whose performances vary with environmental conditions due to weather and soil interactions. In this study, the performance of grape from seven Sangiovese clones was evaluated by analysing grapes from four vineyards in the Chianti Classico Region in Tuscany over the ripening period. In order to assess the oenological eligibility of grape clones, a grape reference model was developed using chemical parameters from commercially available Sangiovese wines, performing a soft independent modelling of class analogy (SIMCA).
